| | "The Magnocellular Theory of Developmental Dyslexia: At first sight, reduced sensitivity to visual motion may seem to have nothing to do with reading. But it indicates reduced sensitivity of the visual magno- celluar system. A total of 10% of the ganglion cells whose axons provide the signals that pass from the eye to the rest of the brain are noticeably larger (magno — larger in Latin) than the remainder (parvo — smaller in Latin) (Enroth-Kugel and Robson, 1969; Shapley and Perry, 1986).
